Urinary Issues: Frequency, Capacity, and Discomfort Explained - Urology

Urinary issues!


Hello, doctor.
Recently, I've been experiencing discomfort while urinating, with frequent urination at first.
However, it has improved a lot.
I've noticed that my urine volume has decreased.
I've been keeping track, and each time I feel the urge to urinate, I only produce between 200 to 300 cc, usually around 250 cc.
Is this a sign of reduced bladder capacity? Isn't it normal to feel a strong urge to urinate at around 400 cc? Additionally, I often feel a sensation of residual urine right after urinating, with a mild discomfort in the urethra and perineum.
Is this normal?

Hello, a urine output of 200-300cc is considered normal.
Generally, most people will feel the initial urge to urinate at around 100-150cc, and a strong urge at approximately 250-300cc.
When the bladder fills beyond 400cc, it becomes nearly unbearable.
However, a few individuals can hold their urine up to 600cc.
At this point, the bladder may have sustained some minor injury.
If you experience a burning sensation after urination, it would be advisable to check your urine for signs of infection.
If you have any further questions or need clarification, feel free to ask, and we can discuss it further.
This message is from Dr.

Hello! It sounds like you're experiencing a combination of urinary frequency, reduced bladder capacity, and discomfort, which can be quite distressing. Let's break down your symptoms and explore potential causes and solutions.

From what you've described, it seems that your urinary frequency has improved, but you're noticing a decrease in the volume of urine you can produce at one time, averaging between 200 to 300 cc. Typically, a healthy adult bladder can hold about 400 to 600 cc of urine before the urge to urinate becomes strong. If you're consistently urinating less than this amount, it may indicate a reduced bladder capacity or other underlying issues.

The sensation of urgency and the feeling of incomplete emptying, or residual urine, can be linked to several conditions. One possibility is bladder overactivity, where the bladder contracts too frequently or without sufficient filling. This can lead to frequent urges to urinate, even if the bladder isn't full. Another potential cause could be bladder inflammation or irritation, which can occur due to infections, interstitial cystitis, or other irritants.

The discomfort you're feeling in the urethra and perineal area after urination could also be a sign of several conditions. It might be related to urinary tract infections (UTIs), prostatitis (inflammation of the prostate), or even pelvic floor dysfunction. These conditions can cause a sensation of burning or aching, particularly after urination, and may also contribute to the feeling of residual urine.

To address your concerns, here are some steps you can take:
1. Keep a Urination Diary: Continue documenting your urination patterns, including the volume of urine and the frequency of urination. This information can be very helpful for your healthcare provider in diagnosing the issue.

2. Hydration: Ensure you're drinking enough fluids, but be mindful of diuretic beverages like caffeine and alcohol, which can increase urinary frequency.

3. Consult a Urologist: Given your symptoms, it would be beneficial to see a urologist for a thorough evaluation. They may perform tests such as a urinalysis, urine culture, and possibly imaging studies to assess your bladder and urinary tract.

4. Consider Bladder Training: If your bladder capacity is indeed reduced, bladder training techniques may help. This involves gradually increasing the time between urinations to help your bladder hold more urine.

5. Pelvic Floor Exercises: Strengthening the pelvic floor muscles can improve bladder control and reduce discomfort. Kegel exercises are a common recommendation for this.

6. Medication: Depending on the diagnosis, medications may be prescribed to help manage symptoms. For example, anticholinergics can help reduce bladder overactivity, while antibiotics may be necessary for infections.

7. Address Anxiety: If you find that anxiety about urination is exacerbating your symptoms, consider speaking with a mental health professional. They can provide strategies to manage anxiety, which may help alleviate some of the physical symptoms.

In summary, while your symptoms may indicate a reduced bladder capacity and discomfort, a thorough evaluation by a healthcare professional is essential to determine the underlying cause and appropriate treatment. Don't hesitate to seek help, as urinary issues can significantly impact your quality of life. Take care, and I hope you find relief soon!
